SHU'TTER-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 600,602, dated March 15, 1898.

Application filed May 13, 1897. Serial No. 636,233- (No model.)

To all whom it may concern:

Be it known that I, ALBERT ASSMAN, a citizen of the United States, residing at Rahway, in the county of Union and State of New J ersey, have invented a new and useful Blind- Fastener, of which the following is a description.

My invention relates to improvements in devices known in the trade as blind-fasteners, and more particularly to that part of the blind-fastener known as the staple, which is fastened to the building and with which the catch engages to hold the shutter in its open or closed positions.

The object of my invention is to produce a device which will elastically connect the shutter-catch to the building to take up any slight movement of the shutter when it is hooked onto the staple attached to the build ing and thus prevent any jarring noise which would occur if the connection were rigid.

One form of device embodying my invention is shown in the accompanying drawings, in which Figure 1 is a vertical section of a buildingwall carrying my improved staple, the staple being shown in side elevation; and Fig. 2 is a horizontal section of a shutter D, showing the catch that catches onto the staple A to hold the shutter open.

It Will be understood that the views are taken at right angles to each other in order to clearly show the parts, and when in use the catch will be at right angles to the wall.

Referring to Fig. 1, O is a side of a building, into which the shank a of the shutter-staple A is screwed. This shutter-staple A is shown as a furcated staple having the arms b c with inturned ends F F, which are surrounded by a spiral spring B, which is held in position by the said inturned ends F F and bridges the gap G between the said inturned ends.

In Fig. 2, D is the shutter, to which the catch E is secured in any usual manner, it being remembered that the catch is shown in plan and at right angles to the position which it will normally occupy for purposes of clearer illustration. When the shutter is closed back upon the building, the catch E will ride over the spring B and will come be tween the arms I) c of the staple and will engage the spring Bin a plane between the ends F F of the staple, so that when the shutter is moved, as by the wind, the spring will act as a cushion and take up the play of the shutter, so as to prevent rattling thereof, the spring forming a. flexible connection between the catch E and the staple.

What I claim, and desire to secure by Letters Patent, is-

1. A furcated blind-staple provided with a spring engaging the furcated' ends of the staple and adapted to be engaged by a shutter-catch so as to form a yielding connection between the staple and the shutter-catch to prevent rattling of the shutter.

2. A furcated staple having arms b c, with inturned ends F F, and a spring intervening between the ends and bridging the gap between the said ends and adapted to be engagedby a catch on a shutter to obviate rattling thereof.

3. A furoated blind-staple combined with a spiral spring held in place thereby and bridging the space between the furcations and adapted to be engaged by a shutter-catch to prevent rattling thereof, substantially as described.

ALBERT ASSMAN.
